Chlorinated Water As A Source Of Chlorate Contamination In Farm Bulk Milk, Lorna Twomey, Ambrose Furey, Bernadette O'Brien, David Gleeson
Chlorinated Water As A Source Of Chlorate Contamination In Farm Bulk Milk, Lorna Twomey, Ambrose Furey, Bernadette O'Brien, David Gleeson
Physical Sciences Publications
The potential for chlorinated water to cause chlorate contamination of milk was evaluated at both laboratory and field level. It was found that for such contamination to occur, direct contact of water and milk was necessary. To minimise the opportunity for chlorinated water to cause chlorate contamination of milk, it is vital to ensure that milk handling equipment is engineered to provide for proper drainage of water and that all necessary steps are taken to prevent the adulteration of milk with water.

Until now there is no systematic study on the effect of the substrate type on the hydrogen silsesquioxane (HSQ) electron beam lithography (EBL) patterning process. We investigate arrays of line structures with varying width and spacing, starting at 10 nm, exposed at varying dose, and developed by salty NaOH and TMAH developers on group IV semiconductor substrates. We demonstrate that the HSQ EBL process on Ge is much more limited in achieving the smallest obtainable features, having optimal uniformity and fidelity, in comparison to Si. Monte-Carlo simulations of the e-beam/substrate interactions for “pure” Si and Ge substrates, and varying content …

In recent years, chlorate has become a residue of concern internationally, due to the risk that it poses to thyroid gland function. However, little is known about its occurrence in dairy products of Irish origin. To address this, a study was conducted in which samples of milk (n = 317), cream (n = 199), butter (n = 178), cheese (n = 144) and yoghurt (n = 440) were collected from grocery stores in the Republic of Ireland. Sampling was conducted across spring, summer, autumn and winter of 2021. Samples from multiple manufacturers of each respective dairy product were procured and …

The findings of this laboratory based experiment suggest that waters with increasing total chlorine levels will have increased chlorate levels and should that water come into contact with milk it has the potential to cause chlorate contamination of said milk. This study provides the information needed to design targeted field based experiments that are required to establish the trends and behaviours of chlorate in water when used as part of the cleaning process on dairy farms and its impact on milk residues and is requisite for the betterment of the dairy industry in terms of its understanding of contamination of …
